Incidence of simple localized esophageal ulcer has been infrequent, but recently, clinical report of the disease has increased with remarkable improvement of diagnostic instrument and handling of endoscopy. Nine patients of simple localized esophageal ulcer with abrupt onset of symptoms and rapidhealing process were clinically studied and observed with the other literatures on the basis af age, sex, site, symptoms, causes, endoscopic findings, microscopic findings, and healing pracess. The results were followed. 1) The eiophageal ulcer revealed variable size and shape and generally localized middle third of esophagus. 2) History of therapeutic drug medication auch as capaule or/and tablet was noted mostly. 3) The symptoms were disappeared with general measures and ulcer lesions were comyletely healed without scar or stricture rapidly.

The pulsed dye laser, emitting at wavelengths of 504nm. for 1 micro sec. at a frequency of 10 Hz. transmitted via a 200 micron in-diameter silicon-coated fiber, was send for fragmentation of urinary stones. The mechanism of stone fragmentation by laser is 'shock wave' formation by laser light ( photoacoustic effect). From Nov. 1988 to Apr. 1990, we performed 89 procedures in 86 patients for the removal of stones (80 procedures in 77 ureteral stones, 3 procedures in bladder stones and 6 procedures in urethral stones). Of the calculi 80 were fragmented to spontaneously passable or easily extractable fragments. There was no significant complications attributable to laser lithotripsy. And there was no significant differences in the fragmentation of stones according to the component. So, we think that laser lithotripsy is a safe and effective modality in management of the urinary stones including renal and upper ureter stones with some exceptions if deflecting ureterorenoscope is available.

Tri- and tetra-cyclic antidepressants are known to cause dry mouth among other several major complications. The present study was designed to compare the degree of reduced salivation due to antidepressants and to explore whether intracellular calcium-increasing agents ameliorate the salivation. Effects of antidepressants and agents increasing intracellular calcium on the cholinergic submandibular secretion and blood flow induced by the chorda stimulation or intra-arterial acetylcholine were observed in anesthetized cats. Effects of antidepressants and calcium-mobilizing agents on K+ efflux were also observed in excised gland slices. The results obtained were as follows: 1. Salivary secretion in response to the chorda stimulation (3 V, 20 Hz, 1 msec) was significantly attenuated by antidepressants in a dose-dependent manner, whereas the blood flow was not affected. 2. Salivary secretion and increased blood flow evoked by intra-arterial acetylcholine (20 microgram/kg) were markedly diminished by antidepressants, the magnitude of which was amitryptyline>imipramine >mianserin in order. 3. Cholinergic salivation was significantly decrease by cyclopiazonic acid, a calcium pump inhibitor of the endoplasmic reticulum, or by BAPTA/AM, a specific intracellular calcium chelator. 4. Caffeine and ryanodine potentiated the cholinergic salivation and ameliorated the depressed salivary secreation due to antidepressants. 5. Calcium ionophore A 23187 ameliorated the depressed salivation due to antidepressants. 6. Antidepressants inhibited the K+ efflux, which were restored by caffeine or A 23187. These results suggest that the depressed salivary secreation due to antidepressants is ameliorated by increasing intracellular calcium levels.

This is a clinical analysis of 48 patients who had tuberculous peritonitis laparoscopically confirmed at the Gastroenterologic Department of the Korea University Hae Wha Hospital from March 1980 to February 1988, and the results are as fallows: 1) The ratio of male to female was 1:1.7, and the age of the peak incidence was the third decade. 2) The freqeent symptoms were abdominal distension (77.1%), abdominal pain (60.4%), and fever (60.4%); others were indigestion (27.1%), diarrhea (18.8%), weight loss (6.3%), abdominal mass (6.3%), vomiting (6.3%), and dysmenorrhea (2.1%). The freguent physical signs were ascites (93.8%) and abdominal tenderness (45.8%); others were palpable mass (8.3%), hepatomegaly (8.3%), and mild jaundice (4,2%). 3) Hematologic findings in mean value revealed 11.8 g/m% in hemoglobin, 6088/mm in WBC, and 36 mm/hour in ESR, 4) Ascitic analysis revealed 1,031 in specific gravity, 5.2% in protein, and 1700/mm in WBC count with lymphocytic predominance (83%). AFB stain and culture were all negative in the specimens less than 20 ml. 5) On chest X-ray, pulmonary Tuberculosis or associated lesions were noted in 19 patients (39.6%). 6) Studded whitish miliary tubercle, omental change, ad adhesions were noted in a mixed nature. 7) Classifications according to laparoscopic finding revealed wet type in 28 patients (58.3%), mixed type in 13 patients (27.1%), and dry type in 7 patients (14.6%); and laparoscopic type was not related with the duration of symptom up to admission. 8) Microscopic finding of biopsy specimens revealed caseous necrosis or granuloma in 43 patient (89.6%) and nonspecific inflammation in 5 patients. In these 5 patients, characteristic gross findings of tuberculous peritionitis were noted. 9) Intestinal perforation was developed in 2 patients.

Extensor pollicis longus tendon rupture is well known as a complication of fracture of the distal radius. There is a higher risk that the tendon of extensor pollicis longus will rupture in undisplaced distal radius fracture than in those which are displaced. We have experienced three cases of rupture of the extensor pollicis longus tendon after undisplaced distal radius fracture. Those were treated by tendon graft and tendon transfers. The results were satisfactory without complications. The patients with undisplaced distal radius fracture should be careful concerned about possibility of rupture of extensar pollicis tendon.
